Application filed an 4, 1910. Serial No. 564,994.

' Be it known that I, MARTIN OLSON, a citizen of the United States, residing at Coeur dAlene, in the county of Kootenai. and State of Idaho, have invented new and useful Improvements. in Automobile Sleighing 'Attachments, of which .the following is a specification.

The present invention provides means whereby a mechanically propelled vehicle may be readily converted into a sleigh, said means embodying a runner, a propeller and a brake.

A further purpose of the invention is the provision of a propeller of unique formation embodying a driver, a guide and a series of yieldable dogs, which, when the propeller is in operation, are caused to take hold of the surface over which the sleigh or machine may he gliding and which dogs when the machine is at rest are'withdrawn,

the dogs yielding when meeting with a non-' yielding object or spot in the surface so as V to prevent injury or a disabling oft-he propeller.

The invention consists of the novel fea- I tures, details of construction and combination of parts, which hereinafter will be more particularly setforth, illustrated in the accompanying drawing, and pointed out in the appended claims.

Referring to the drawing, forming a part of the application, Figure 1 is a side view of a runner and propeller embodying the invention. Fig. 2 is a transverse section on the line a':v of Fig. 1. Fig. 3 is a detail view of a portion of the propeller. Fig. 4 is a detail perspective view of one of the dogs.

Corresponding and like parts are referred to in the following description, and indicated in all the views of thedrawing, by the same reference characters.

The runner comprises side portions 1, which are transversely spaced and a tread portion 2 connecting the lower edges of the side portions 1. The side portions 1 of the runner slope upwardly intermediate of their ends and terminate in hubs 3, which are adapted o receive the axle upon which the propeller is mounted. Braces 4 are inter posed between the outer endsof the hubs 3 and the lower portions of the side members 1 and serve to strengthen and stay the outer ends of the hubs. The runner may be constructed in any manner and preferably conabutting against the bers 12 supportdogs by sists of separate pieces rigidly connected, the

are placed together and secured in any manner, either by belts or rivets. Hubs 6 project outwardly from the disks 5 and fit I loosely within the hubs 3 of the runner and are adapted to be secured to the axle ;7 so

as to rotate therewith. The driver is provided around its outer edge with points 8 to which bars 9 are connected in a manner to have a limitedpivotal and longitudinal movement. The bars 9 have their. inner ends forked and the forked membersprovided with longitudinal slots 10 through which pins 11 pass, ported in openings formed in the projections 8. Springs ,11 mounted upon the inner ends of the bars 9 havetheir outer ends connected with said bars and their innerends points 8, said springs exertm an outward pressure on the bars toyiel ingly'hold the dogs 13 inioperativo positlon.

A guide is loosely'mounted upon the hubs 6 of the driver and is formed of two plates or circular members 12 whichare transversely paced and have the driver arranged between them. The circular plates or memdogs 13, which are pivoted at 14c thereto, the opposite ends of the dogs having a limited playso as to be projected beyond the outer edges of the members 1901" said pins beingsup-..

gageinent with the slippery surface over' i which the machine equipped with the pro-- peller may be gliding. the bars 9 are pivotally connected to the V means of pinsor bolts 16 which 'pass through slots 17 formed inthe outer edge portions of the members 12, thereby adm1tting of the swinging ends of the dogs 13 moving so as to occupy a position within the plane of the outer edges'of the guide or to be projected hevond the outer cdges of said guide. The outer ends of the bars 9 are forked and receive the bars 9 have an approximate tangential ar- The outer ends of pins or bolts 16. The

rangement; and a turning movement ofithedriver independently of'theguidee-causes the active ends of the dogs 13 eitherto be pro- 'jejctedor retracted. When thedriverlis ro-.

tated forwardly the bars 9 are-pushed outwardly and project the bit'in'g edgesjof' the;

' dogs 13, whereby. they engage the icy sur c ment-to the vehicle;

face-andimpart a positive propelling moves 7 When the propelling force is cut off the guide movesbackward by the action of-the springs 11, thereby with drawing the biting edges of the dogs/13.

This enables the machine to coast;

The brake consists of a'dog 18 pivoted intermediate of itsends, to the runner. 'A' spring 19' cooperates with the dog 18v to hold vthe same-out of action. A rockshaft 20-is lower faceofthe- -runner to-biteinto the surface and bring thejmac-hine to' rest. The 'rocksh'aft-2O may be operated-in-anyman v I i inner ends'to t e drlveritohavezapivotal ner..i- "From the foregoingdescription, taken connection withdhe'accompanying drawing,
